Now that Rimac has a production car ready to go, there seems to be no holding it back. It's put together the most electrifying booth in Geneva, quite literally speaking. Next to the 1,088-hp Concept One supercar is the even faster, more powerful Concept S, the One's "evil twin," along with a matching, unleashed version of the Greyp G12S electric bike. All in all, close to 2,500 horses with current-spiked manes are dashing around Rimac's booth.

In developing the Concept S, Rimac tapped into the knowledge it gained running the Tajima Rimac E-Runner at last year's Pikes Peak International Hill Climb. Like that car, the Concept S packs over a megawatt (1,341 hp) of electric motor power, helping Rimac shoot right past the Finns in angling for the title of world's most powerful electric supercar. The dual front and dual rear electric motors work with Rimac All Wheel Torque Vectoring S (R-AWTVS) to optimize the distribution of up to 1,328 lb.ft (1,800 Nm) to the four wheels. All that output meets the ground via a set of Pirelli P Zero Trofeo R track tires after running through two single-speed transmissions up front and two double-clutch two-speeds at the rear. An 82 kWh 650V battery pack provides the energy.

"We wanted to use the experience and knowledge from Pikes Peak and offer our customers a unique, race-like experience," explains Rimac founder and CEO Mate Rimac. "The Concept S pushes the levels of performance to the extremes. Focusing on performance, the set-up of the R-AWTVS system has been adapted to give the driver the ability to use the maximum out of the tires and aerodynamics."

To keep the Trofeo Rs properly planted on the asphalt below, Rimac has given the 1,384-hp Concept S a hardcore aerodynamics kit that it says adds 34 percent more downforce over the Concept One. The full kit, with its front splitter, air deflectors, side skirts, rear diffuser and rear wing, also gives the Concept S its extreme track car look.

The Concept S weighs 110 lb (50 kg) less than the Concept One thanks to a trimmed down interior and changes in the carbon fiber composition. Its 3,968 pounds (1,800 kg) are distributed over a 42/58 front/rear ratio.

The interior is more track-focused, but the driver still enjoys access to a high-tech infotainment system. Not your average voice-texting, Pandora-playing infotainment set-up, this one is built around helping the driver engage in the most spirited, high-performance driving possible. He or she can flip through menus and adjust settings for the R-AWTVS system, brake force, torque distribution and more, changing the car's character from mellow cruiser to closed-track drifter. The display also shows information gathered from the more than 500 onboard sensors around the car, data that is also sent to the cloud via built-in 4G, where the driver can access and analyze it later.

All that weight, power and aero optimization results in improvement upon the Concept One's already impressive performance, with Rimac estimating a 2.5-second 0-62 mph (100 km/h) sprint, 5.6-second 0-124 mph (200 km/h) run and 227 mph (365 km/h) top speed.

As if the production Concept One and Concept S aren't enough to ensure a steady flow of Geneva visitors, Rimac is also showing a Concept S version of its Greyp G12S electric super bike. More than just a cosmetic update, the concept bike follows the "evil brother" form of the Concept S as a high-performance, no-holds-barred edition.

"Our aim was to emphasize the technology and performance with the unique design that matches the new Concept S hypercar," says Mate Rimac. "The electronically limited maximum speed of 70km/h (43.5 mph) is now unblocked so it can follow the Concept S's stellar performances. We wanted to showcase how supercar technology can trickle-down to other applications to create new and exciting products."

The elimination of electronic speed limitation proves a big boost to the 12-kW G12 Concept S, giving it a 55-mph (90-km/h) top speed to make it one of the world's fastest e-bikes. Those looking for miles over miles-per-hour can expect the same 75 miles (120 km) of motor range from the 1.5 kWh lithium-ion battery that's available on the standard G12S. Like the production bike, the G12 Concept S relies on a fingerprint sensor for security.
